It depends on the school you attend. The networking effect is bigger than just the people you attend class with, although those connections are often very valuable. Most MBA students aren't studying for entrepreneurship. They're someone who has already had success in the business world and are going to advance their career. Having a network of connections across business domains can be very valuable.

Obviously it depends on the startup. B2B businesses would get more value out of those connections. I stated that it's likely the biggest benefit of business school, not the only benefit. A true cost-benefit analysis would look also at the knowledge acquired as well as the strength of the alumni network.
